Production Possibilities Frontier Chapter 1, Lesson Three Cont.
Recall • Opportunity cost is the value of the best forgone alternative
PPF • The production possibilities frontier (PPF) is a diagram that shows production combinations available to an economy given finite factor inputs and technology • It is a model economists use to illustrate the concept of opportunity costs
Simple Linear Model • Say you are a house painter and you and your crew can paint either 20 small houses or 10 large houses in a week. You can also paint a number of combinations of the two. • It takes the same amount of time to paint one large house as it does to paint 2 small houses.
Simple Linear Model • So what is the opportunity cost of painting one large house? • What is the opportunity cost of painting two small houses?
Simple Linear Model • We use these points on a graph to find the PPF 10 Large Houses 5 0 0 10 20 Small Houses
Simple Linear Model • All points on the line are said to be efficient because they represent the maximum number of houses that can be painted with available resources and technology • You could paint any combination of houses on or inside the PPF
Simple Linear Model • These points inside the model are attainable, but inefficient—you are not working up to your capabilities. • Points outside of the PPF are unattainable and cannot be reached due to the lack of resources required to reach those points.
Simple Linear Model • You could increase your PPF if you increase your factors of production, or resources.
Non Linear Model • Most real world examples are curved when they are put on a PPF. This is because of the law of increasing opportunity costs. • Law of increasing opportunity costs states that as the production of anything rises, the opportunity cost of forgone production will eventually increase.
Non Linear Model • It gets harder and harder to produce as you increase production. It will cost more.
Non Linear Model Point C: Unattainable Must Increase Factors of Production to Reach Guns Point B: Efficient and Attainable Point A: Attainable but inefficient Butter
